DNGO - Audiobook Cover Image Creator for Laravel5

Hello all!

We have developed a Steem dapp to create a collectively produced, multilingual and publicly accessible audiobook archive. We call it DNGO (Decentralized Non-Governmental Organization). We would like you to give us a hand to apply book covers onto our web site. If you are familiar with Object Oriented Programming with PHP7 (Laravel5 and Doctrine2 Based) you can find details below.

If you are looking for more information about the project, here is the introduction post:

Our public repository is available here on GitHub!
https://github.com/dngo-io/books

But for further usage, we are expecting your pull-requests here:

Requirements & Things You Need

For sure it has to be ready to go and could be used in the project with composer.

Book blank covers and any visual materials are accessible here (all the files are located in Book Covers folder):
https://dngo.io/dngo-documents/dngo-visual-materials.zip
Book cover graphic design request is located here:
https://steemit.com/utopian-io/@meskoze/dngo-book-cover-request
The code should produce book cover for each book in the archive. Selection of a template can be randomly. For examples in use, scroll a bit down to How It Will Be? section.

How It Will Be?

Book cover templates were also produced by Steemit Community with Utopian. Each post have example usage samples in the body.

It must be a composer friendly package which can be extendable with more than one background image / template.
It should be configurable for each blank template so it can fit title and author text into each template (text margin, font-size etc.)
It should handle special or accent characters in the text (like ö, ç, ğ, ü...)
It must be developed on PHP GD library
